I voted for option #2. I just seems like BS to say you can win the WW title say, when both fighters had to come in at 145. Seems any top contender could claim that they could have beaten either of those fighters if they were at 147 while the opponent was at 145. So, how could that champion be the legitimate 147 champ!

I wonder about the ability to have 12 round fights if it's not for a belt though? I guess it's apparent that rules and and tradition are quite transient, so I suppose that doesn't matter either.

Also, while I like a lot of these fights that are being made, because they do keep things interesting; it would actually be refreshing to see someone try to unify and dominate a division for the long haul.
